January 28
Henry IV Absolved by Pope at Canossa
Emperor Henry IV's penitential journey across the Alps culminated in his dramatic submission to Pope Gregory VII at Canossa Castle, temporarily resolving a crisis in the Investiture Controversy.
Summary
In the midst of the Investiture Controversy, a bitter conflict over who held authority to appoint bishops in the Holy Roman Empire, Emperor Henry IV faced excommunication by Pope Gregory VII in 1076. This left Henry politically isolated as German princes threatened rebellion. Desperate to regain legitimacy, Henry crossed the Alps in winter with his wife and young son, enduring harsh conditions to reach Canossa Castle in northern Italy where the pope was staying as a guest of Countess Matilda of Tuscany. Upon arrival on January 25, Henry stood penitently outside the gates for three days in the snow before Gregory granted him an audience. On January 28, 1077, the pope lifted the excommunication, allowing Henry to return to the Church and temporarily stabilizing his rule, though the underlying tensions persisted.
Context
The Investiture Controversy emerged in the mid-eleventh century as part of the Gregorian Reforms, through which popes sought to free the Church from lay control and assert exclusive authority over the appointment of bishops and other clergy. Henry IV, who became king of Germany in 1056 and later Holy Roman Emperor, defended the traditional imperial right to invest ecclesiastical officials, a practice that generated revenue and political loyalty for the crown. The conflict sharpened after Gregory VII's election in 1073, when the pope's decrees against simony and lay investiture directly challenged Henry's prerogatives, particularly in the disputed see of Milan.
What Happened
By late 1076 Henry faced excommunication and the threat of deposition by German princes assembled at Tribur. Advised to seek reconciliation before the pope could reach Germany, Henry set out from Speyer in December with his wife Bertha of Savoy and their young son Conrad. He traveled south through Burgundy, crossed the Alps via the Mont Cenis pass in severe winter conditions, and reached Canossa Castle in the Apennines of northern Italy on 25 January 1077. There Gregory VII was staying as the guest of Matilda, countess of Tuscany and a staunch papal ally.
Henry appeared before the castle gates as a penitent and remained outside for three days. On 28 January Gregory received him, heard his submission, and lifted the excommunication, restoring the king to communion with the Church.
Aftermath
The absolution allowed Henry to return north and rally support among wavering German nobles, delaying any immediate deposition. Yet the reconciliation proved fragile; the investiture dispute resumed within months, and Henry later convened a synod that deposed Gregory and elected an antipope. Matilda of Tuscany continued to shelter and finance the papal cause in Italy.
Legacy
Canossa came to symbolize the temporary ascendancy of papal over imperial power in the High Middle Ages and the ritual humiliation of a secular ruler before ecclesiastical authority. In the nineteenth century Otto von Bismarck invoked the episode during the Kulturkampf, declaring that Germany would never again submit to papal demands in the same manner.
Why It Matters
The Walk to Canossa exemplified the dramatic contest between secular and ecclesiastical power during the High Middle Ages, influencing the balance of authority in Europe for centuries. It became a lasting symbol of political humiliation and submission, later invoked by Otto von Bismarck in the 19th century to reject papal interference in German affairs. The event underscored the papacy's temporary ascendancy while highlighting the fragility of imperial authority amid feudal rivalries.
